Application filed September 22, 1919. Serial No. 325,579.

T 0 (all whom it may concern:

Be it known that we, Mosns MOSLER and CARL BARTELs, citizens of the United States, residing at New York, New York county, New York, and Hamilton, Butler county, Ohio, respectively, have invented certain new and useful Improvements in Safes, of which the following is a specification.

This invention relates to improvements in safes applicable to safes or vaults formed of steel castings, and the invention will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1 is a front elevation of a safe embodying an exemplification of our present invention; and

Fig. 2 a. horizontal section of the same in the plane of line a of Fig. 1, half of the door appearing in plan;

In the drawing 1, indicates the shell of the safe:

2, its front door opening with a tapering inward reduction, and, in the exempliflcation, illustrated as being circular:

3, a rearward prolongation of the margin of the door opening:

4v, a flange projecting inwardly from the prolongation 3, a small distance inwardly of the smaller diameter of the door-openin" 2:

o, a groove, of dovetail section, in the prolongation 3 just at the front of flange 4:

6, the wall of the inner compartment of the safe, the same having an exterior dimension adapting it to pass rearwardly through the bore of flange 4:

7, a forward prolongation of the wall 6 of the inner compartment:

8, an external flange on the forward extremity of prolongation 7, this flange being of dovetail cross-section and having such major diameter as will enable it to pass rearwardly through the smallest diameter of door opening 2 and be engaged in front of flange 4::

9, a filling strip tightly fitting between the bottom of groove 5 and the periphery of flange 8:

10, a tapering portion of the bore of prolongation 7, this tapering portion 10 and the door-opening 2 forming the stepped doorjamb of the safe:

11, a thread upon the bore of prolongation 7 to the rear of the tapering bore 10:

12, the front plate of the door, its riphery closely fitting the doorway 2:

13, the rear plate of the door:

14, a peripheral flange extending from the rear plate 13 to front plate 12 of the door, the periphery of this flange closely fitting the tapering bore 10 of the prolongation of the wall of the inner compartment:

15,;1 rearwardly extending flange on the margin of front plate 12 of the door, this flange surrounding the front extremity of flange 14 of the rear door portion, and havmg its rear in seating engagement against the front end prolongation 7 of the wall of the inner compartment:

16, a filler strip tightly fitting the space between the bore of flange 15 and the periphery of the forward extremity of flange 14c: and

17, a rearward extension from back plate 13 of the door, this extension being provided with an exterior thread engaging the thread 11 of the wall of the inner compartment.

The shell of the safe with its front and its rearward prolongation margining the door opening, is to be cast in one piece and the inner structure is to be cast in another piece and after these two parts are assembled and the filler driven to place then the combined structure becomes a practically integral one, and the machining employed in constructing the door-jamb may be done, if desired, after these two parts have been assembled.

Similarly the front and rear portions of the door are assembled and permanently united by the filler 16, and the finishing of the door to accurately fit the door opening may be done after the two door parts are thus assembled. The door is illustrated as of the screw type, but it is to be understood that the rear member of the door may be provided with devices other than a screw for securing it in place in the door-jamb. If it be desired that the door be provided with packing, then such packing may be provided in front of the filler 9, the filler in such case being shallower than the space it occupies, the front portion of such space being filled with the desired packing material.

The door opening is illustrated as being circular, a form essential in the screw type of door, but the principles of our invention may be filled, if desired, with fireprooling or other material."

lVe cla1m:

1. A shell provided with a door opening and a rearward prolongation atthe margin of said opening, an inner COHIPzLltIHGIlt having a wall adapted to pass through said opening, ineia ns for securing the front portion of said wall within said rearward prolonoation and a door havin a Jeri Jher V fitting partly within said opening in the shell and partly within the front portion of said wall.

2. A shell provided with a doorway and with a rearward prolongation of the margin of the doorway, an inwardly projecting flange at the rear of such prolongation, an inner wall-provided at its front with an out wardly projecting flange adapted to pass through said doorway and'engage against the front of the inwardly projecting flange o'l said prolongation, means for securing the twoflanges to each other, a door having a periphery fitting the door opening in the shell and iittingwitl1i-n the front portion of the inner wall, and means for securing the door againstoutward displacement from the door opening, combined substantially as set forth.

3. A shell provided with a doorway and 1 with a rearward prolongation of the margin of the doorway, the inner surface of such prolongation being provided with a groove deepened at its rear, an inwardly projecting flai'ige at the rear of such groove, an inner wall provided at its iront with an outwardly pro ecting beveled flange adapted to pass 'th'rrmgh said doorway and engage against the front ot the inwardly pro eetlng flange of said prolongation, a filler tightly flitting the space between said last-mentioned flange and the bottom of said groove, a door having a peripherylitting the door opening in the shell and fitting the front portion of the inner wall, and means for securing the door against outward ('lisplaoenient from the door opening, comlnnedsubstantially as set forth.

4. A shell provided with a tapering doorway and with a rear-ward prolongationof the margin of" the doorway, an inwardly projecting "flange at the rear o'f such'prolongat ion, an inner wall provided at its front with a tapering bore and with an outwardly projecting flange adapted to pass through said doorway and engage against the front oflthe inwardly projecting flange of said prolongation, means for securing the two flanges to each other, a door having a periphery fitting the door opening in the shell and fitting within the front portion of the inner wall, and means for securing the door against outward displacement from the door opening, combined substantially as set forth.

5. A shell provided with a doorway and with a rearward prolongation of the margin of the doorway, an inwardly projecting flange at the rear of such prolongation, an inner wall provided at its front withan outwardly projecting flange adapted to pass through said doorway and engage against the front of the inwardly projecting flange of said prolongation, means for securing the two flanges to each other, a door having a periphery fitting the door opening inthe shell and fitting within the front portion of the inner wall, and an exterior thread upon the rear portion or" the door engaging an interior thread in said wall, combined substantially as set forth.

'6. A she'll provided with a tapering doorway having an inwardly projecting flange at its rear, an inner compartment havin a wall adapted to pass through the bore of said flange, an outwardly projecting flange at the front of the wall of the inner compartment adapted to pass through said tapering doorway and seat rearwardly against the front of the inwardlyprojecting flange of the shell, the front of the compartment having a tapering doorway, means for securing the inner compartment permanently within the doorway of the shell, and a door having a periphery fitting the doorway in in the shell and covering the means of unitmg the inner wall to the shell.
